Consumer acceptance of Italian or New Zealander lamb meat: an Italian case study.
No full textA Central location test was performed to compare heavy Apennine lamb meat to New Zealander lamb meat in order to create a Protected Geographical Indication for lamb meat. Roasted New-Zealander and heavy Apennine lamb legs were tested by 106 consumers according to the following experimental plan: blind phase (B) without any possibility to recognize the meat type tasted, expected phase (E) in which were described the characteristics of the two types of meat without tasting, informed phase (I) in which the tasted meat was recognized in provenience. Results showed in a nine point scale of appreciation for flavour, juiciness and overall pleasure, the highest values in Apennine lamb meat. B test showed the highest value for overall pleasure (P<0.01). Interaction, Italian lamb x Informed test showed the highest values for all the parameters except for overall liking for which Italian lamb x E test showed the highest values. About foreign lamb meat B test showed higher values than I and E test. Information about lamb meat origin showed disconfirmation for tenderness in Italian lamb meat. Foreign lamb meat showed a positive disconfirmation for flavour and overall pleasure, that confirm the better perception by consumers in blind consumption than in the informed one
Effect of LNA integration on endocrine and metabolic parameters in dairy cattle
No full textIn a field trial the effect of long term supplementation of different levels of estruded linssed and energy levels on milk yeld and plasma concentrations of insulin, T3,cortisol, leptin, glucose and non esterified fatty acids (NEFA) in dairy cow in early lactation, were evaluated. Fifth seven italian holstein fresian cows reared in Parmigiano Reggiano cheese area, homogeneous for lactation number, days in miilkings (DIM) (41±12d), BCS (3.17±0.14) in productive level in the previous lactations, were allotted into three experimental groups, in different farms, with similar management system (Control group - C 1.45 Mcal NEI/Kg DM, 280 g/d Omega-Lin® - Mignini &Petrini 0280; 1.51 Mcal NEI/Kg DM, 450 g/d Omega-Lin® - Mignini &Petrini 0450; 1.56 Mcal NEI/Kg DM) and feed isonitrogenous TMR diets. Omega-Lin® contained 70% of exstruded linseed. Blood samples were taken by coccigeal vein and blood parameters evaluated. Fixed effect of diet, parity and hear within diet were tested. Parity showed a significant effect only for milk yeld and T3, while diet influenced significantly milk yield, T3, leptin and NEFA. Milk yield was higher in 0450 group compared to the control one (43.61 vs 35.51: P<0.01). T3 showed the highest level in 0450 group if compared with C group (1.32 nmol/l vs 1.07 nmol/l: P<0.01) while 0280 group showed an intermediated level. NEFA as indicators of body lipids mobilization showed the highest in C group (0.50 mmol/l) and lower in 0280 group (0.29 mmol/l) (P<0.01) while 0450 showed an intermediated level. Opposite results were found for leptinwhich showed the highest level in 0280 group and the lowest in C group (4.08 ng/mL vs3.08 ng/mL: P<0.05) while 0450 group showed an intermediate level. No significant differences were found in the other parameters although cortisol and insulin are key players in the control of intermediary metabolism and glucose as indicator of energy balance. In conclusion leptin, T3, NEFA levels in 0450 group put in eveidence a better energy utilization for milk yield although the trend of these parameters showed in 0280 group should be explained by a probably different genetic valueof the cows among farms. Further analyses will be desiderable

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

No full textLetter from R. R. Zellick, Assistant Trust Officer at The Anglo California National Bank of San Francisco, to Joseph R. Goodman, regarding property owned by Dave Tatsuno. Zellick mentions a dispute between current tenants and Tatsuno, and that Tatsuno has asked Goodman to help locate trustworthy tenants.Personal correspondence, organizational records, government documents, publications, and other papers created or collected by Joseph R. Goodman documenting the forced removal and incarceration of Japanese Americans during World War II, as well as organized resistance to incarceration. Included in the collection are records of the Japanese Young Men's Christian Association and the Japanese American Citizens' League in San Francisco, including papers of the Japanese YMCA's executive secretary Lincoln Kanai; Sakai family papers; Goodman's correspondence to and from Japanese American incarcerees, organizations opposing forced removal and incarceration of Japanese Americans, the War Relocation Authority, and others; publications, photographs, and ephemera from the Topaz Relocation Center, where Goodman taught high school; War Relocation Authority records and publications; and newspaper clippings, pamphlets, and reports about forced removal and incarceration created by various government, religious, and civic organizations, in California and nationwide
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
